ad623 not linear?

I'm currently using an ad623 to amplify a signal thats usually between 0 and 500mV.

The Chip is supplied with 4.5V DC.

REF is connected to ground.

Between the Rg Pins is is a 10k Resistor 5% Resisitor this sshould result in a Amplification of 11.

But when tested the Amplification isn't linear at all. It seems like the output is moving towards a 2V limit.

What could be the cause of this?
